    实体类:

    1. package dto;
    3. public class Td51CustRisk {
    6.     private String custNo;
    8.     private String custCnName;
    10.     private String orgKey;
    12.     private String custType;
    14.     public String getCustNo() {
    15.         return custNo;
    16.     }
    18.     public void setCustNo(String custNo) {
    19.         this.custNo = custNo;
    20.     }
    22.     public String getCustCnName() {
    23.         return custCnName;
    24.     }
    26.     public void setCustCnName(String custCnName) {
    27.         this.custCnName = custCnName;
    28.     }
    30.     public String getOrgKey() {
    31.         return orgKey;
    32.     }
    34.     public void setOrgKey(String orgKey) {
    35.         this.orgKey = orgKey;
    36.     }
    38.     public String getCustType() {
    39.         return custType;
    40.     }
    42.     public void setCustType(String custType) {
    43.         this.custType = custType;
    44.     }
    45. }

    解释：
    将list通过java8特性 改成map的形式—-将custNo作为map的key值，保证唯一性。

    Map custRiskListMap = td51CustRiskList.stream().collect(
    Collectors.toMap(w -> w.getCustNo(),
    w -> w));
    再通过for循环—-根据custNo做匹配即可
